<cid:part1.08010705.09060809@ra.rockwell.com>Hello,
I spotted this during my tests with -rt on arm. The -rt patch contains
some better tools
to diagnose problems with locks and some other things...
Original code tries to take semaphore in BUG_ON and then free the memory
with this semaphore.
Patch is against 2.6.17.
